Hi, I have an application (think hardware driver) that runs as a particular (GUI) user. Now, if that user is switched out using Fast User Switching or the screen lock has engaged, I want to prevent the driver from working (as the user sitting in front of the computer with access to the hardware is obviously not them).
The only documented API I've found is NSWorkspaceSessionDidResignActiveNotification etc., but this doesn't help me because it only notifies me when the state changes, it doesn't let me obtain an initial state (I suppose I could assume if I'm running as a user, my session is active, but would prefer actually knowing). I've also found that CGSessionCopyCurrentDictionary() contains an undocumented key that lets me know whether the screen lock is engaged, but that reports the screen as not locked when the user is still logged on, but switched out using fast user switching. Is there any official, supported way to determine whether the user my app is running as actually owns the screen and screen lock is not engaged that I could use for this purpose? Since I only need to know the current state when the user actually triggers my device, a polling API would be fine.
